下面是我用来编译代码的bash命令：

$mxe/usr/bin/i686-w64-mingw32.static-gcc \
../CLI/*.cpp ../kernel/*.cpp ../kernel/core/*.cpp \
../shared/*.cpp ../shared/export/*.cpp ../unqlite/*.c \

我将尝试解释命令应该做什么： 第一行是MinGW的gcc编译器，后面是要编译的源文件。下一行应该链接不同库的MXE include和lib目录。之后是“-l”标志，以包括实际的库。我需要的库是boost、Qt5、fftw、eigen和hdf5

我还将包括用于编译Linux代码的bash命令，该命令确实可以正常工作：

gcc ../CLI/*.cpp ../kernel/*.cpp ../kernel/core/*.cpp \
../shared/*.cpp ../shared/export/*.cpp ../unqlite/*.c \
-o OpenPSTD-cli -lstdc++ -pthread -lfftw3f -lhdf5 -lhdf5_hl \
-I/usr/include/eigen3 -I$HOME/Qt/5.9.1/gcc_64/include \
-I$HOME/Qt/5.9.1/gcc_64/include/QtCore -I$HOME/Qt/5.9.1/gcc_64/include/QtTest \
-I$HOME/Qt/5.9.1/gcc_64/include/QtGui \
-L$HOME/Qt/5.9.1/gcc_64/include/QtCore -L$HOME/Qt/5.9.1/gcc_64/include/QtGui \
-lQt5Core -lQt5Test -lQt5Gui -fPIC -lm \
-lboost_unit_test_framework -lboost_chrono -lboost_system -lboost_timer \
-lboost_regex -lboost_iostreams -lboost_serialization -lboost_filesystem \
-lboost_thread -lboost_date_time -lboost_atomic -lboost_program_options \
-DQT_NO_VERSION_TAGGING -DQT_GUI_LIB -DQT_CORE_LIB -DQT_SHARED

从错误消息中我了解到，问题在于未正确包含Qt5和hdf5库（这确实是问题吗？）

我在谷歌上搜索过类似的问题，听起来这些库的顺序不正确。我试着移动“-lQt*”和“-lhdf5*”标志，但我一直得到相同的错误。我还验证了所有库都安装在MXE中，并且所有库的库和头文件（.a和.h）都存在于包含的目录中

---

如何解决错误消息？我对错误发生原因的理解是否正确？

请参阅以下答案：您下载了使用Visual Studio编译的QT库而不是MinGW库吗？正如对该问题的公认答案所示，我确实安装了MinGW库（通过MXE）。我没有在我的项目中使用Visual Studio或qmake。
